Anatol Posted June 20, 2011 Report Share Posted June 20, 2011 Fellow Inspectors, I am looking for some advice regarding the replacement of my antique boiler. Home is middle group brick and block town home. 1300 Sf not including finished basement. In wall convectors. I did the heat loss calculation and came up with 16,785 BTU/hr loss. The old oil fired boiler unit had enough waste heat to warm the basement, I may have to add a heat source there to make up for that. I am planning on installing a gas fired 90%+ condensing boiler. Several I have seen while inspecting had variable input from 30-90K BTUs depending on need. Does anyone have any thoughts of the best quality brand, heat exchanger metal, best warranty or other factors. All advice is welcome...

hausdok Posted June 20, 2011 Report Share Posted June 20, 2011 Your home is small enough that a hi efficiency tankless water heater married to a small plate exchanger and a couple of circulators might work; however, for what you'll pay for a 90+ condensing water heater plus the mods you'll need to marry it to that system, I think it would make more sense to look at one of the new compact wall-hung condensing boilers that are designed for hydronic systems.

Anatol Posted June 21, 2011 Author Report Share Posted June 21, 2011 I am looking at the wall mounted units. I was hoping that someone had some experience with them. I have only seen the Crown and Buderus models in the real world, but I know there are more out there... Anatol Quote Link to comment Share on other sites More sharing options...
